Not all net trap systems perform the same
Small Design Differences Have Big Field Consequences
Use these specifications and evaluation tools to compare net trap systems on performance, durability, and safety.
Poorly designed traps increase labor, prolong damage, and reduce future capture success as pigs learn to avoid them.
What drives trap performance
Why design details matter
Small design differences directly impact escape rates, safety, and durability. As other net trap options have entered the market, these are the factors that determine whether a system performs safely and reliably over time. Choosing the wrong system increases cost, risk, and failure rates in the field.
Containment vs. escape
If pigs can chew or tear the net, they will escape.
- Knotless netting eliminates chew points
- Heavy-duty inner layer reduces chew-outs and tears
- Top cap prevents escapes over the top line
- Square mesh orientation holds shape under load
- Inner net significantly stronger than outer net for redundancy
- Knotted net gives pigs something to chew through
- Diamond mesh allows flop and stretch under pressure
- Same-weight inner and outer layers offer no true redundancy
- Higher escape rates and partial sounder capture educate pigs and reduce future trapping success
- Knotless HT polyester
- Square mesh orientation
- Outer net: ≥130 KGF
- Inner net: ≥303 KGF (2.3x stronger)
- Sewn-in top cap
Structural integrity and operator safety
If the net lifts or the wall drops, pigs escape and operators are at risk.
- Internal anchor stakes prevent net lift ("wave" effect)
- Mid-post cam straps secure net to posts
- Non-stretch top rope maintains perimeter tension
- Minimum 10 T-posts to limit unsupported wall sections
- Secure U-clamp mounts that lock to posts
- No internal anchors means net flies up when pigs hit the wall
- No mid-post cam straps means the net is not taut between posts
- Nylon top rope stretches under load, losing tension
- Fewer posts or a greater distance between attachment points create large unsupported wall sections
- Ring-style mounts can flip off posts during capture
- Increased operator risk and agency liability exposure
- 5 internal anchor stakes
- 10 T-posts with zinc-plated U-clamp mounts that lock to post
- 10 mid-post cam straps (≥450 kg capacity)
- Polysteel top rope, 2,300 kg break load
- 15% elongation (vs. high-stretch nylon)
Entry behavior
If the skirt bunches or catches, pigs won't commit to trap entry.
- Smaller mesh (≤1.5 in) prevents snout catch
- Pleated skirt with sewn-in rope maintains consistent shape
- Smooth, uniform entry around the full perimeter
- Skirt bunches without sewn-in rope tension
- Uneven entry points cause hesitation
- Pigs don't fully commit, reducing capture rates
- ≤38.1 mm (≤1.5 in) mesh
- Pleated skirt with sewn-in rope
- 3.4 m inner diameter
Durability and cost over time
A cheaper trap that fails in the field costs more over time.
- UV-stabilized bonded materials
- High-strength, tear-resistant netting
- Reinforced seams and connections
- Corrosion-resistant hardware
- Lightweight netting tears under field stress
- Short service life in sun exposure
- Frequent replacement drives total cost up
- ≥5 year service life in full sun
- All textiles UV-stabilized bonded
- Galvanized or stainless hardware
- 1-year limited warranty

Every feature exists because earlier designs failed
Single-layer nets led to chewing-related escapes
Early dual-layer systems reduced but did not eliminate escapes
Knotless woven materials significantly improved durability and reduced escapes
Mesh size refinement and sewn pleats improved entry behavior and capture rates
Internal net sewn along top and bottom edges solved piglets getting trapped between layers
Internal anchor stakes and mid post cam straps eliminated lift and escape dynamics under load
